A quiet revolution is taking shape in the world of physics, and it doesn’t rely on exotic particles or massive particle colliders. Instead, it begins with something much more familiar—sound.

In the ETH experiment, self-oscillations (blue-red) cause sound waves (green, orange, violet) to travel through the circulator only in one direction. Credit: Xin Zou Researchers at ETH Zurich have ...

According to the team, this discovery not only advances understanding of time crystals but could also help understand natural processes like circadian rhythms.

A team of researchers has for the first time successfully used lasers to generate guided sound waves on the surface of a microchip. These acoustic waves, akin to the surface waves produced during an ...

Optical neural networks may provide the high-speed and large-capacity solution necessary to tackle challenging computing tasks. However, tapping their full potential will require further advances. One ...

Even more surprisingly, plants themselves can produce sound waves. Recent studies have shown that stressed plants, such as those that are thirsty or injured, emit tiny clicking or popping sounds at ...
